Refer to the exhibit. P3 and PE4 are at the edge of the service provider core and serve as ABR routers. Aggregation areas are on either side of the core.
Which statement about the architecture is true?

  • A. To support seamless MPLS, the BGP route reflector feature must be disabled.
  • B. If each area is running its own IGP, BGP must provide an end-to-end MPLS LSP.
  • C. If each area is running its own IGP, the ABR routers must redistribute the IGP routing table into BGP.
  • D. To support seamless MPLS, TDP must be used as the label protocol.

Which component is similar to an EVPN instance?

  • A. router distinguisher
  • B. MPLS label
  • C. IGP router ID
  • D. VRF


Answer : D

Why do Cisco MPLS TE tunnels require a link-state routing protocol?

  • A. The link-state database provides segmentation by area, which improves the path-selection process.
  • B. The link-state database provides a data repository from which the tunnel endpoints can dynamically select a source ID.
  • C. Link-state routing protocols use SPF calculations that the tunnel endpoints leverage to implement the tunnel.
  • D. The tunnel endpoints use the link-state database to evaluate the entire topology and determine the best path.


Answer : D


Refer to the exhibit. BGPsec is implemented on R1, R2, R3, and R4. BGP peering is established between neighboring autonomous systems.
Which statement about implementation is true?

  • A. BGP updates from the iBGP peers are appended with a community of local-as.
  • B. BGP updates from the all BGP peers are appended with a community of no-export.
  • C. BGP updates from the eBGP peers are appended with an additional AS path value that is statically set by the domain administrator.
  • D. BGP updates from the eBGP peers are appended with a BGPsec attribute sequence that includes a public key hash and digital signature.
